Australia is dealing with the aftermath of a 16-hour terror siege that occurred just three months after the country's terrorism alert was raised to its highest level in a decade.
Early on Tuesday morning, gunshots were heard from inside Sydney's Lindt Chocolate Café, where a lone gunman took 17 people hostage on Monday morning at 9:45am local time. Six hostages escaped at the time of gunshots, around 2am, prompting policemen on either side of the building to storm the café.
Armed with guns and stun grenades, police took down the gunman, identified as 50-year old Man Haron Monis, an Iranian refugee. Two hostages were killed during the incident, including the café manager, a 34-year old man. Andrew Scipione, police commissioner for the state of New South Wales, told media that an investigation would be carried out to determine whether the victims were killed by the gunman or if they died in cross-fire.
